Connecting the DC Wiring Harness to the DC Power Socket on the EPS-150DC

After the DC wiring harness is connected to a permanent DC voltage source by a qualified, licensed
electrician, you can remove, replace, and maintain the EPS-150DC unit without further electrician
assistance.
WARNING!
Always be sure that the DC circuit is de-energized before connecting the DC wiring harness to the DC power socket.
To connect the DC wiring harness to the EPS-150DC unit:
